Producing kilometer-long nanowire and nanotube arrays. It is not often that prefix multipliers kilo- and nano- come together; and when they do exclusively in the opening chapters of physical sciences textbooks the point being made is that the universe around…

We introduced a novel optoelectronic nose (digital photonic nose) which utilizes an array of infrared transmitting hollow core photonic band gap fibers for detection of several volatiles. The fibers in the array have distinct transmission bands depending on their photonic…

High-power fiber lasers operating at NIR and MIR wavelengths have attracted great interests recently due to their unique applications in defense, medical, and industry. We have been developing special Yb-doped active fibers for high-power fiber lasers since 2012.

Highlights from Literature

Nanotechnology is steadily moving from the laboratory to the marketplace and is now enabling or enhancing products in a variety of sectors, including clothing, electronics, clean energy technologies, and automobiles. Although a great deal of progress has been made in expanding our fundamental understanding of nanoscale materials and devices, there are still challenges associated with designing and fabricating
integrated nanosystems. [ NNI 2016 Strategic Plan ]

These days, a scientist has to publish a steady stream of research articles to be “successful.” But two new studies argue that that kind of pressure promotes sloppy science at the expense of careful work. “The problem that we face is that the incentive system is focused almost entirely on getting research published, rather than on getting research right,” “Once you have bad practices they can propagate and ruin the scientific process and become dominant. And I think there’s some truth to it, unfortunately.” The publish-or-perish culture may be having negative consequences already. [ view more ]

The research sector loves talking about excellence but is it best for science? It is almost impossible to work in research without hearing the word excellence. Universities use it in their mission statements and funding agencies name programmes after it. In a forthcoming paper, a group of open access researchers and advocates, have taken a sharp look at the science world’s pervasive use of the word. They go so far as to call it a fetish and conclude that it’s having negative consequences for research. “Excellence is not excellent, it is a pernicious and dangerous rhetoric that undermines the very foundations of good research and scholarship,” [ view more ]

- Research needs less ‘excellence’, more competence

Did you ever measure a smell? Can you tell whether one smell is just twice strong as another? Can you measure the difference between two kinds of smell and another? It is very obvious that we have very many different kinds of smells, all the way from the odour of violets and roses up to asafetida. But until you can measure their likeness and differences, you can have no science of odour. If you are ambitious to find a new science, measure a smell.

- Alexander Graham Bell, 1914

Dogs’ sense of smell is more amazing than we thought – Knowing the importance of smells in general — and my smell, in particular — to my dogs has changed our lives together. In the morning they sniff me awake; I let them lick (a way for them to absorb molecules for smelling). When I return home from a trip, I reach down to greet them — and let them smell me back. Now I even take a sniff of them myself. What I would do to see the world they smell. [ view more ]
